# GRE Math : How to add even numbers

## Example Questions

### Example Question #1 : Even / Odd Numbers

The sum of seven consecutive even integers is 0.

Column A: The product of the seven integers

Column B: 2

Column A is greater.

Column B is greater.

The relationship cannot be determined from the given information.

The two quantities are equal.

Column B is greater.

Explanation:

For the sum of 7 consecutive even integers to be zero, the only sequence possible is –6, –4, –2, 0, 2, 4, 6. This can be determined algebraically by assigning the lowest number in the sequence to be “y” and adding 2 for each consecutive even integer, and then setting this equal to zero.

y, y + 2, y + 4, y + 6 . . .

The product of any number and 0 is 0.

Therefore, column B must be greater.

### Example Question #2 : Even / Odd Numbers

and  are both even whole numbers.

What is a possible solution for ?

Explanation:

If  and  are both even whole numbers, then their addition must be an even whole number as well. Although  is an even number, it is not a whole number and could therefore not be a solution. This means the only possible solution would be .
